The Howler™ siren adds deep tones to primary sirens in fire, EMS, and police vehicles, enhancing intersection safety. Compatible with 100/200-watt sirens.

The Howler low-frequency tones are synchronous with your primary siren tones to penetrate high noise, high traffic situations. The Howler Siren Amplifier module uses the primary siren speaker output wires and divides the frequency down to one of three frequency bands via dip switch.

An effective added layer of warning when used with your 100/200 watt siren amplifier. Howler provides deep, low frequency tones, which are able to penetrate other vehicles, alerting drivers and pedestrians of your approach.
